AT&T vs Verizon iPhone : our two cents

Considering a switch from AT&T to Verizon's iPhone? We just made the jump, and if so you'll definitely want to check out Gazelle, they buyback used technology (and paid over $350 for a used AT&T iPhone4). As for Verizon iPhone service? Well, VZW does have reception almost everywhere in LA and rarely drops calls, but MMS/picture messages often fail or take 2-3 attempts, and there's no removable SIM card if you are an international traveller (not to mention the current inability to  simultaneously handle data & phone usage).
